Erm...today the paper not much resistant....very long winded thought n tricky....mind game too...thinking tat the question so long must have a lot of steps but den actually very short onli....cold sweat sia...1b really suck...my Ho and H1 input wrongly le...at least can get 80 marks ba...not bad le....
come out frm tat room...wow sia..relieved man...jol n jen all say tat question 1b is Z test but actually is T test...all bluff by the sample standard deviation which is = S for the T test formula...erm...lecturer also not stupid ba...put two Z test for us to do also....
Test ans : 1A -> 2 tailed test , 'Z' test, do not reject Ho
1B->Upper tailed test, 'T' test, do not reject Ho (SL n AL s' Ans)
2-> RCB...'F' 16.++, Fcz = 3.89, reject Ho.
Hope u all get the correct ans too :-)
